Porous carbon materials rich in defects are promising candidates in energy storage and conversion applications. Herein, a facile template‐free approach is reported for the synthesis of a two‐dimensional (2 D) mesoporous carbon material derived from fullerene (C 60 ) microsheets (FMSs) through simple heat treatment. The sample obtained at 1000 °C (FMS1000) shows a large surface area of 1507.6 m 2 g −1 owing to the presence of mesopores and rich defects, which promote electron and mass transfer in the electrocatalytic process of the oxygen reduction reaction (ORR), showing an excellent performance with an onset potential of 0.95 V, a half‐wave potential of 0.85 V, and long‐term durability of 2000 cycles, comparable to the performance of commercial Pt/C. Moreover, FMS1000 displays a remarkable supercapacitive property with a specific capacitance of 330.7 F g −1 at 0.2 A g −1 and good long‐term stability with a capacitance retention of 97 % over 50 000 cycles. Thus, a practical strategy for the production of mesoporous carbon materials with different morphological structures and porous defects as high‐performance energy materials is advanced.
